SNOWPLOW.

Application filed. November 7, 192'?.r Serial No. 231,592.

The present invention relates to improvements in snow plows, and hasreference more particularly to an improvement over the snow plowdisclosed in my -prior Patent No. 1,641,2'23, September 6, 1927.

One ot' the important objects of the present invention is to provide asnow plow which includes a tan casing open at its front side and towhich secured a sectional housing which is also open atits front side,auger forming knives being adapted ior rotation within the housing, andcooperating at their rear inner ends with tan blade Jforming buckets;the tan casing being provided with a peripheral snow discharge pipe.

A further object is to provide a snow plow of the above mentionedcharacter wherein an elbow is supported on the upper end of the snowdischarge pipe, and is adapted tor hori- Zontal swinging movement, anadditional pipe being connected to the elbow for conveying the snow toany particular point at the sidev of the road where the snow gathered bythe plow may be deposited.

A still further object of the invention is to provide a snow plow of theabove mentioned character, which is simple in construction, inexpensive,strong and durable and further well adapted to the purpose for which'itis designed.

Other objects and advantages of the invention will become apparent fromthe following description when taken in connection with theaccompanying' drawings.

In the accompanying drawings forming part ot this application and inwhich like numerals indicate like parts:

Figure 1 is a top plan view of the snow plow embodying my invention.

Figure 2 is a vertical sectional view through the tan casing, and thefan blade forming buckets arranged therein as well as through the outletpipe and the elbow and the horizontally supported discharge pipe.

Figure 3 is a sectional view through the fan casing, and the frustoconical housing showing in top plan the auger forming knives, and thefan blade forming buckets associated therewith, and

Figure 4t is an enlarged fragmentary sectional view showing theconnection between the adjacent edges of the sectional housing 4i'or theauger forming knives.

In the drawings wherein for the purpose of illustration is shown thepreferred embodiment of my invention, the numeral 1 designates generallymy improved snow plow, the f same being adapted to be mounted'on thetront of a tractor, motor car, or the like in the manner as set out inmy prior patent mentioned above. The snow plow includes a sectionaltrusto-conical housing 2 which may consist ot two, three, or moresections, as is desired. Laterally extending lianges such as are shownat 3 `and 4, respectively, are forme d on the complementary sections ofthe hood or housing 2 and these flanges are securedtogether in abuttingrelation by suitable bolt and nut connections shown at 5.

The bottom wall of this frustoconical hood or housing 2 is formed so asto present a horizontal front edge to which is hingedly secured ahorizontal plow blade 6 that is equipped at its forward edge withforwardl extending spaced teeth 7 that will bite into the snow and causethe same to be fed upwardly into the housing in the manner also moreclearly disclosed in my prior patent.

This hood or housing is open at its respective ends and a lateral flangeextends outwardly from the rear edge of each of the sections ofthe hood,as shown at 8 and extending rearwardly from the flanges 8 are the ears 9in the manner clearly illustrated in Figure 3.

A substantially cylindrical fan casing 10 which is open at its frontside abuts the outer edge portions of the flanged rear end of the hoodor housing 2 and the rearwardly extending ears 9 are disposed againstthe inner peripheral face of the fan casing. Suitable securing meanssuch as is shown at 11 extends through the forward edge portion of thefan is connected to the frusto-conical hood, in the manner clearly shownin Figure 3.

Extending upwardly from the periphery of the circular fan easing 10 isthe relatively short outlet pipe 12 and adapted for rotary movement onthe upper end of this outlet or exhaust pipe is the elbow 13. A band orcollar 14 encircles the upper portion of the outlet or exhaust pipe 12and any appropriate means may be provided for maintaining the elbow inposition on the outlet or exhaust pipe at its upper end againstaccidental displacement therefrom.

An elongated discharge pipe 15 has its inner end tted in the outlet endof the elbow 13 for conveying the snow to the side of the road, and byswinging the elbow to the positions shown in the dotted lines, the snowmay be discharged from the plow in any predetervcasing and the ears,whereby the fan casing niined direction. However, there is provided onthe fan casing a pair of upwardly disposed brackets 16 and 17, on theupper ends of which are arranged the horizontally alined rings or bands18 and 19, respectively, through which the discharge pipe v is slidableand these brackets and the bands or rings carried by the upper endthereof will support the discharge pipe in a stationary horizontalposition, as clearly shown in Figures 1 and 2 of the drawings.

A driven shaft 20 extends centrally through the fan casing and thesectional housing or hood 2 and this shaftis driven by the sanne means.and in the saine inanner as set out in rnyprior Patent No. 1,641,723.secured Von the forward end portion of this driven shaft- 2() fordisposition adjacent the forward open end of the sectional housing orhood 2, and this hub rotates with the shaft. plurality of arins extendradially from this hub 21 as illustrated at 22 with reference moreparticularly to Figure 3. A similar hub 23 is secured on the shaft 2Orearwardly of the aforementioned hub 21 and this hub 23 ispreferablyarranged adjacent the closed rear side' of the fan casing 10as clearly shown in Figure 3. A series of arins 2li extend radiallyfromthis hub 23 and is clearly illustrated in Figures 2 and 3 of thedrawings.

A plurality of auger forming knives designated by the nuineral 25 aresecured at their larger forward ends to respective radially eX- tendingarms 22v associated with the forward hub 21. F our of such knives areemployed and the saine extend rearwardly in the sectional hood orhousing 2 through the open rear end thereof. The inner ends of theseauger forming knives are so constructed as to provide fan blade formingbuckets 26 which are secured to the respective radially extendingarnis'2fl associated with the rearmost hub 23 il hub 21 is neeaeoi andas clearly illustrated in Figure 3, these fan blade forming buckets areoperable within the fan casing.

It is obvious that when the shaft 20 is operated and the snow' plow isnioving forwardly over the snow covered surface, the snow enteringI theforward end of the hood will come in contact with the rotatable augerforniing knives and these knives will convey the snow 1earwardly intothe fan casing where the buckets 26 will carry the snow around in arotary manner to discharge the saine through the tangentially extendingoutlet or exhaust pipe 12, and through the elbow 13 and the dischargepipe 15 to point at the side of the road.

1While l have shown the preferred einbodinient of iny invention it is tobe understood that ininor changes Corning within the scope of theinvention niay be niade without departing from the spirit of theinvention or the scope of the appended claiin.

l-laving thus described the invent-ion, what l Claini as new is t ln a.snow plow, a housing open at its forward and rear ends, a fan casingopen at its front side and secured to the rear end of the housing, anoutlet pipe extending upwardly frein the periphery of the fan casing, ahorizontal discharge pipe connected at its inner end to the upper end ofthe outlet pipe7 upstanding brackets carried by the fan casing,horizontally alined bands arranged on the brackets through which thehorizontal pipe extends and is supported, auger forming knives mountedon the shaft for rotation within the housing to feed the snow to the fancasing, and a fan unit mounted on the shaft for rotation within the fancasing to force the snow out throughthe outlet pipe` ln testimonywhereof l affix my signature;
